GraphStudioNext

Follow steps #1 to #7 to configure BlackMagic Decklink Video ports, you may need to repeat steps #4 to #6 in order to find the correct settings of the input.

The card input configuration MUST match the actual feed.

Note: Make sure the ActControl service is stopped and no other application is using the Blackmagic card during configuration!

1) open Windows Explorer and go to c:\Actus\Bin\Tools, find graphstudionext.exe, Right-Click on it and select “Run as administrator” to open the application.

2) Once GraphStudioNext is open, click on the “Graph” menu and select “Insert Filter”

3) On the popup menu, click the pulldown menu of “(ALL) DirectShow Filters” and select "Video Capture Sources" and then you will be shown only the relevant filters for configuration. Select the port required for configuration (eg: Decklink Video Capture) and click on the "Insert" button

         

4) After the Filter is inserted, Right-Click on it and select “Properties...”

5) Under the “Video Format” click on the pulldown options and select the correct configuration that matches the input, then click “Apply” to confirm and “OK” when done.

7) After click the Play, the “ActiveMovie Window” will open, if you are seeing a Black Screen, then the configuration does not match the input. You would need to delete everything that was added after the Capture Pin, and repeat Steps 4 to 6 and change “Video Format” input and try again until you see a video playing.
